Diatom silica is a form of biogenic opal (SiO2.nH2O, Figure 1) containing oxygen, silicon, carbon and nitrogen isotopes that can be used in lacustrine and marine paleoenvironmental studies. Since diatoms bloom following a seasonal pattern defined par... Read More about Stable isotopes from diatom silica.

Geochemical analyses (x-ray fluorescence, δ13C and C/N ratios) were used to reconstruct early Holocene environments (between 10685 and 7260 cal. yr BP) at a small lake near Holebudalen, southern Norway. Results show a period of increasing stability,...

Reconstructing hydrological variability in Lake Baikal during MIS 11: An application of oxygen isotope analysis of diatom silica (2008)
Presentation / Conference Contribution
Mackay, A. W., Karabanov, E., Leng, M. J., Sloane, H. J., Morley, D. W., Panizzo, V. N., Khursevich, G., & Williams, D. (2007, April). Reconstructing hydrological variability in Lake Baikal during MIS 11: An application of oxygen isotope analysis of diatom silica. Presented at Isotopes in Biogenic Silica (IBiS), Nottingham, UK

In this paper we reconstruct hydrological variability in Lake Baikal during Marine Isotope Stage 11 (MIS 11) (427-362 ka BP) from oxygen isotope analysis of diatom silica. Highest δ18Odiatom values are found during MIS 11.3, highlighting the dominanc...

Towards the systematic simplification of mechanistic models (2006)
Journal Article
Cox, G., Gibbons, J., Wood, A., Ramsden, S., & Crout, N. J. (2006). Towards the systematic simplification of mechanistic models. Ecological Modelling, 198,

Mechanistic models used for prediction should be parsimonious, as models which are over-parameterised may have poor predictive performance. Determining whether a model is parsimonious requires comparisons with alternative model formulations with diff... Read More about Towards the systematic simplification of mechanistic models.
